Toad and frog rod photocurrents.
The size of Bufo marinus and rana pipiens rod photocurrents is similarly affected by changes in flash intensity. These species' rods also produce similar photocurrents during steady illumination, to which they both adapt. Thus, their transduction mechanisms are probably alike. Previous reports that frog and toad rod responses are different may have resulted from the use of an unusual procedure in which the rod outer segment was isolated from its inner segment.
